Abstract

A method is given for determining electron-density and collision-frequency distributions in the lower ionosphere from VLF and LF sounder data. Error limits are placed on the distributions by mapping the standard errors of the data into error limits on the ionosphere parameters. Interpretation of the error limits is discussed, especially in regard to the relationship between the resolution of a distribution and its error band. Examples are given that illustrate the method.
